摘要： PURPOSE:To manufature a free-cutting steel of high quality by uniformly dispersing metals to be added such as Pb and Bi in a molten steel with a small loss by melting with a burner and blowing into the molten steel. CONSTITUTION:When a free-cutting steel is continuously cast, a molten steel in a ladle 1 is charged into a tundish 2 through a long nozzle 3, and metals to be added such as Pb and Bi in a hopper 6 are melted with an oxyacetylene flame from a spraying torch 7 and blown on the surface of the molten steel in the tundish 2. The blown Pb and Bi are uniformly dispersed in the molten steel, and the molten steel is charged into a continuous casting mold 5 through an immersion nozzle 4. Since Pb and bi which are largely different from the molten steel in specific gravity are uniformly contained in the molten steel, a free-cutting steel casting of high quality is obtd. by continuous casting.

摘要： PURPOSE:To draw twin dummy bars in a linear state and to improve productivity by forming the outside of bar-like bodies that constitute the twin dummy bars into a slightly thin walled shaped and bringing driving rolls into linear contact with the thin walled parts of the bar-like bodies. CONSTITUTION:Twin dummy bars 9 consisting of a pair of bar-like bodies 10, 10 are constituted of many links 17 connected with linear bodies 15, 16 by means of pins, spacing pings 19, etc., and are made into a slightly thin walled spape by forming tapered surfaces 18 on the outside parts of the outer body 15 and a tail part 10A. The bars 9 are inserted into the mold (not shown) in a continuous casting installation from the part 10A, and when the head part 10B arrives at the prescribed position in the mold, charging of molten metal is started. At the same instant, the lower part of the bars 9 is inserted and held with rotating driving rolls 1A and is pulled downward. The rolls 1A can draw the bars 9 in a linear state by linear contact with the tapered surface 18 of the outside body 15, etc. and by point contact with the inside body 16.

摘要： PURPOSE:To connect dummy bars in a continuous casting device for twin blooms and triple blooms automatically and surely to chanin-like bodies and to improve the efficiency of continuous casting work by incorporating an upward insertion system by specific construction for said dummy bars. CONSTITUTION:In the stage of casting two pieces of blooms continuously and simultaneously with a continuous casting device for twin blooms, in an ingot conveying route consisting of many rolls 37 right under a mold 36, a backing plate 38 is mounted at the position facing the working rods 10 of the operating bodies 6 of chain-like bodies 2, 3 connecting to dummy bars 1. A dummy bar car 39 is moved to transfer its insertion ports 39a to right above a mold 36. The connecting rod 15 of the bars 1 thereon is inserted into the square grooves of the bodies 6. Further, the bars 1 are inserted into the mold 36, and when the head parts of the rods 10 about on the plate 38, the connecting rod 15 connects the bodies 2, 3 to each other by means of a lock lever device, so that the two dummy bar heads 2b, 2b are moved downward simultaneously in the mold 36.

摘要： PURPOSE:To fuse coating film parts and to form a continuous body by abutting the end faces of plural composite materials formed by layering coating films having the lower melting point than base materials and welding the abutted base material parts of the composite materials. CONSTITUTION:In welding and joining the base material end faces, a means to use the coating composite materials P whose insides are covered with the coating films 2 having the lower melting point than the base materials 1 is adopted. As a result, in welding and joining the pipes P which are coated on the inside, for instance, since inside coating layers can be joined only by management from the outside without carrying out any management from the inside, operation is extremely simple. Moreover, because of fusion between the coating films 2, there is no inclusion of a different kind of material and even in microstructure, the boundary is not almost found and the uniform and continuous pipes P which are coated on the inside are obtained. As a result, the long size pipe can be manufactured.
